Difference in these 2 Bells?

[HarrisonTX]

Can any tell me a difference in these two bellhousings.
Both lakewood blow proofs. I see the 15000 Has more mounting hole, i guess for different motors.

The lakewood 77-150. $200 and looks like it'll work just fine.

The Lakewood 15000, Almost identical and $150 more. It does come with a block saver plate.

Anyone see something im not?

FYI, this is for a Gen1 small block, and a Tremec TKO

Only the second one is SFI rated.

Ah.. I see that now.
Im sure the non SFI one with work. Ive heard too many horror stories of exploding flywheels and injured ankles.
This motor will see some high RPM, and most likely an aluminum flywheel.
$200 for a scattershield isnt too bad.

In your car, you want Lakewood 15015, not 15000.

Its actually the datsun 260z

although, im sure with my 3,000 RPM launches, im running some risk in the malibu with that aluminum bell.

Minor derailment, is it because of the fork angle? Looks like a regular straight one would work here, no?

Yes, the straight fork works in the 15000 and 15015.

In the Malibu, you need the 15015 so that the pocket in the fork aligns with the lower pushrod properly.
